PF00134Cyclin, N-terminal domain (Cyclin_N)Cyclin, N-terminal domainCyclins regulate cyclin dependent kinases (CDKs). Swiss:P22674 is a Uracil-DNA glycosylase that is related to other cyclins [4]. Cyclins contain two domains of similar all-alpha fold, of which this family corresponds with the N-terminal domain.Domain

CycT2 is the regulatory subunit of the cyclin-dependent kinase pair (CDK9/cyclin T) complex, also called positive transcription elongation factor B (P-TEFB). This domain adopts s cyclin box fold consisting of five helices and a short C-terminal helix [2].
